Sending an Emergency Alarm with Voice to Follow

transmission period, the radio ignores the PTT press and 
remains in Emergency mode.
NOTE: If you press the PTT button during hot mic, and 
continue to press it after the hot mic duration expires, 
the radio continues to transmit until you release the 
PTT button.
